<p>该流程过程中主要是在enhance方法内进程代理（拦截器）的创建。具体的拦截器接口有<code>InstanceConstructorInterceptor</code>,<code>InstanceMethodsAroundInterceptor</code>,<code>StaticMethodsAroundInterceptor</code>,然后在上面三个接口的子类中有些会实现<code>EnhancedInstance</code>接口进行动态属性添加。而最主要的三个接口的实现类的调用是通过<code>newClassBuilder.method(junction).intercept</code>方法内部调用的。</p>
